Efficient access to conjugated 4,4'-bipyridinium oligomers using the Zincke reaction: synthesis, spectroscopic and electrochemical properties
journal contribution
posted on 2023-06-09, 12:01 authored by Long Chen, Helen Willcock, Christopher J Wedge, František Hartl, Howard M Colquhoun, Barnaby GreenlandBarnaby GreenlandThe cyclocondensation reaction between rigid, electron-rich aromatic diamines and 1,1'-bis(2,4-dinitrophenyl)-4,4'-bipyridinium (Zincke) salts has been harnessed to produce a series of conjugated oligomers containing up to twelve aromatic/heterocyclic residues. These oligomers exhibit discrete, multiple redox processes accompanied by dramatic changes in electronic absorption spectra.
